Let's divide 996720 by 72
The aim is to understand the frequency of 72 in 996720.

Step 1:
9 divided by 72 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 72

Advancing to step 2:
72 goes into 99 1 times with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 72 from 99, we get 27.
Include the next digit (6) from the dividend after 27, then repeat: 276 / 72

Advancing to step 3:
72 can be fit into 276 3 times, resulting in a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 216 from 276 and we're left with 60.
Append the next digit (7) from the dividend to 60 and continue with: 607 / 72

Step 4:
72 goes into 607 8 times with a remainder of 31.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
If we subtract 576 from 607, we get 31.
Take the next digit (2) from the dividend and append it to 31, then repeat: 312 / 72

Advancing to step 5:
If we divide 312 by 72, we get 4 and a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 1384.0
Subtract 288 from 312 to get 24.
Bring next digit (0) of the dividend behind the 24 and repeat the process: 240 / 72

Going ahead to step 6:
72 can be fit into 240 3 times, resulting in a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 13843.0
The remainder is 24 after subtracting 216 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
When dividing 240 by 72, we get 3 with a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 13843.3
If we take 216 away from 240, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 8:
The number 72 fits into 240 3 times, leaving a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 13843.33
Subtract 216 from 240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 13843.33 and a remainder of 0.024.
